[users@httpd] Side effect of blocking images
Hi,
I don't want my images to be linked from other sites. So I added this to
my mod_rewrite settings:
RewriteCond %{HTTP_REFERER} !^http://my-server.com/.*$ [NC]
RewriteRule .*\.jpg$ - [F]
Does this setting have any side effect? I mean, is there any possibility
the user's browser doesn't pass 'Referer' value? Or firewall rule that
change the Reference on browser maybe? Anyone has comment on this
setting? Please help.
Thank you,
Batara

Sure. Just replace the above RewriteRule with something like
RewriteRule /images/my.jpg /images/no-you-dont.jpg

Would it be possible to display an alternate image for those that are
trying to hot link to images on my site?
Thanks

Yes, you could be blocking people who choose not to send Referer. You can
eliminate this problem by also acceping an empty HTTP_REFERER. There
could also be people who deliberately change the referer, but since I
can't think of a good reason to do that, I wouldn't mind blocking them.
